Affirmative,The plane won't descent until you tell it to by rotating the alt knob. If you are in VNAV, the plane will descend after crossing the T/D waypoint, and you have moved the knob to a lower alt. If not in VNAV, you have to active LVL CHG or V/S after rotating the knob to begin your descent.
